To all whom. imag concern.'

`Beitlznown that we, AJAMES D. fADAMs and AUGUST IG. JOHNSON j=,citizens .of .the United States, and-residents ofMonessen, in the countyof-Westmorclandrand State of Pennsylvania, have invented a new audusefulImprovement in Cores for WTire-:Reelm and we do hereby declarethefollowing to be a full, clear, and exact description thereof` (Qurinvention relates to cores or internal supports for wire-reels.

The object of ourzinvention is toprovide a core or internal supportforreelsyformed of wire or other suitable material by means of whichlthereelis heldefrom collapsing or bending under the strain of the windingofthe wire upon the reel, and at the same time one which is quicklyadjusted into position within the reel, and readily removed therefromwithout sticking.

To these ends my invention comprises, generally stated, a base-piece,collapsible arms connected to said base-piece and to an outer supportingmember, whereby when said base-piece is seated on a fixed support thearms are distended, and when the coremember is removed, said arms moveinwardly or collapse to permit of the ready withdrawal of thecore-member from the reel.

Referring to the accompanying drawing Figure 1 is a perspective View ofa reel to which our improved core is particularly adaptable; Fig. 2 is asectional elevation of my improvedcore; Fig. Sis a sectional viewshowing the core in position within the reel and the reel mounted on thewinding device; and Fig.4is a section on the line M Fig. 3.

In Fig. 1 of the drawing, we have illustrated a form of reel which hasbeen made the subject of an application for Letters Patent of the UnitedStates filed by us, Serial No. 729,845. This reel consists of the endmembers 2 which are formed of a single piece of wire bent in the form ofa star with the radiating arms 3. The tie-members 4 connect theend-members 2, said tie-members having the loops 5 at eachend thereofwhich are slipped over the arms 3 and engage the seats or depressions 6in said arms. When the reel is put together in this manner, it forms areel in which the members are securely locked together, but in order toprevent the collapsing or bending of the tie-` members in reelingthcwire thereonyitis found desirableto employ` a core-member or internal.support during the winding operation. A base-piece or inner member 71isprovided `withthe square opening 8. Toggle-fingers Qarepivotcditothelugs 10 on thebase-piece 7 and to the lower-ends of thearms v11. Theupper ends of the arms llaare pivoted toitheiugs 1-2onthcouter member 13. 'This outer member `has the square opening 14 andisuprcvided `with the groovcslfandltito receive-the looped ends ofthettedllembers 4;:and the arms 3 of the end-members 2, respectively.

fThe member 7 is provided withthe stops 417 with which thetoggle-fingers 9 are adapted to engage when the core-piece is seated inthe reel and, furthermore, the iingers 9 have the nibs 18 which areadapted to engage the member 7 and control the move` ment of saidtoggle-iingers.

The core-member is inserted in the reel by passing it down through theopen center of said reel and the operator grasping with his hands theouter member 18. lhen the inner member 7 strikes the Hoor or othersupport, the weight above will tend to lower the arms 11 and thetoggle-fingers 9 until said toggle fingers engage the stops 17, and thearms 11 move out into practically parallel position as indicated in Fig.3. The reel with the core inserted in it is then adjusted in the frame19 of the twisting and winding device, said device having the member 2Ocorresponding to the outer member 13 and with which the inner member 7contacts, while the grooves 21 receive the wires of the end member andloops of the tiemember, as clearly shown in Fig. 3. rl`he member 20 isconnected to the bevel gearwheel 22 by the screws 23. This bevel-gear 22has the square opening 24 and the hub 25 which extends through the frame19. The bevel-pinion 26 in the frame 1f) meshes with the bevelgear-wheel 22. A square shaft 27 is then inserted in the square openings14, 8 of the core-member, and the square opening 24 oi' the bevelgear-wheel 22. A yoke 27a on the frame 19 is then brought in position tobe held in place by the thumbscrew 28 to hold the shaft 27 in position.Uien power is applied to rotate the pinion 26, the gear-wheel 22 isrotated and with it the reel and its core-member.- The wire Wound aroundthe wheel in the ordinary manner and at the same time twisted and thepressure of the winding operation 1s sustained by the core-piece so thatthe reel is held from collapsing and bending due to the strain createdby the windingoperation. When the reel has been wound to its fullcapacity, the machine is stopped and the shaft 27 is removed whichpermits the reel to be taken from the machine and the corepiece is thenwithdrawn. To accomplish this the member 13 is grasped and the reel andcore jolted which will move the toggleingers 9 to the position shown inFig. Q, while at the same time the arms 1l will collapse and moveinwardly, so as to free themselvesv whereupon the core may be readily'withdrawn from the reel, which is then ready for shipment. Thecore-piece is then ready to be inserted in another reel, when the aboveoperation is repeated.

What we claim is:

inner member and an outer member, toggle- -inner member and anoutermember, togglengers connected to said inner member, stops on said innermember in the path of said toggle-ngers, and arms connecting saidtoggle-fingers with said outer member.

3. A core-piece for reels, comprising,r an inner member and an outermember, toggleinpgers connected to said inner member having nibs attheir inner ends, and arms connected at the outer ends of saidtoggle-fingers and to said outer member.

' In testimony whereof, we the said JAMES D. ADAMS and AUGUST G. JOHNSONhave hereunto set out hands.
